Yeah -- that could work too. I don't think there would be any problem
with having two ports of the same name except for case differences,
but ICBW.

Well, that very much depends on the details of what the vendor code
actually does. If you're lucky, you just copy it into place and it
will pick up the settings from the www/rt3 port at runtime. If you're
unlucky you'll have to duplicate large chunks of the option management
stuff from the rt port. But as the porter this is something you'll
have to think about, even if it's only to say "Hah! I don't need to do
anything!"
What you won't have to do is restate all of the /dependencies/ -- as
far as I can see, your port just needs to depend on www/rt3 which
should pull in all the necessary perl modules etc.

What build process is that? You said there was nothing much to do
except unpack the distfiles and copy the files into place. Remember
too that everything needs to work when installing a package as it does
when installing a port.

A good trick is to edit the Makefile in ${WRKSRC} so that it uses make
variables set in the port Makefile and automatically passed into the
Make environment. Eg. you can patch the ${WRKSRC} Makefile to use
${PREFIX} itself, rather than trying to substitute in the value of
${PREFIX} at build time.
